IN VEN TOR W E MUan/ess,

W0 Y r A TTORNE YS fiange 25-covering and protecting the portion or' the block vwhich lies adjacent the lateral face of' the tread 10 of the rail. As shown in Figure l, a part of the filling 14 of asphalt occurs between thislflange 25 and the adjacent lateral face of the tread of the rail l0. Gripping shoulder lugs 26 are punched from the flanges 2li and 25 and are embedded in the concrete making up the block l2.

rvThe pavingblock may be cast in sections to suit'xthe need ,of the particular railway,

4although the ,size of' the standard block ,would lprobably be in width, about one-half the distance from center to center of the rails ci.tl1e.track,.andbetween(one to three feet in lengt'h. This of' course applies to the blocks ll. The blocks 12 could be of any suitable length andv width.

j The height of' :both the blocks 1l and 12 is preferably the saine as the height of the rails of the track. lheseblocks would find ,theirgreatest utility vin 'sections where paving bricks are not easily secured, as in such places it would greatly facilitate the layingY of the-track and would not necessitate the Ytying up of traffic for any considerable time.

I claiml. A paving block for use with street railway tracks having a protecting shoulder` for the .corner thereof` disposed adjacent the rails of the track, said protective shoulder comprising a pair of angularly disposed flanges, eacliof said flanges being provided- Withfa'plurality of gripping lugs embedded inthe body of the block.

2. Azpaving block for use with street railway tracks having a .protecting shoulder for the cornerthereotl disposed adjacent the rails of' the track, said protective shoulder consisting of ,a fiat flange and a curved fiange angular-ly disposed with respect to each other.
